Complete sets of mobile operation software for in-field calibration of electric energy meter

Abstract

The analysis and record of data for traditional in-field calibration of electric energy meter relies on artificial work, which will easily lead to data error due to human factors and unable to realize standardization of calibration. The complete sets of mobile operation software for in-field calibration of electric energy meter is embedded the process of in-field standardized operation, which can standardize the in-field calibration of electric energy meter and realize automatic identification of wiring mode and calibration methods of electric energy meter. It establishes the multiple data intelligent diagnostic model based on information such as current cutoff、 lose of phase、 voltage-loss and severe three-phase unbalance. By analyzing and comparing with the user data of Power User Electric Energy Data Acquire System, the model can automatically identify and diagnose abnormal power consumption behavior like stealing electricity. It also establishes a model for distinguishing the abnormal operating state of electric energy meter, which can realize automatic distinction of abnormal operating state of electric energy meter. Introduction Electric energy meter is a metrology apparatus for commercial exchange between electric power enterprises and customers, and calibration of electric energy meter is the duty of electric power marketing management which is very important to electric safety and power management. For a long time, the calibration personnel took the calibration instrument to the scene of the electric meter calibration, recorded the calibration data in the notebook, analyzed and screened the calibration data artificially, and then went back to the office to put the calibration data into the computer. The in-field calibration and background jobs in the office was performed separately, which cannot realize standardization of calibration and high-efficient work and analyzing and screening the calibration data artificially can easily lead to the data error of calibration. The complete sets of mobile operation software for in-field calibration of electric energy meter is embedded the process of in-field standardized operation, which can standardize the in-field calibration of electric energy meter. It also uses a variety of encryption technology to access intranet system securely, realizing a seamless connection with the Marketing Information System. The software employs an intelligent recognition and matching technology of calibration methods and establishes database of calibration methods of electric power meter to realize automatic identification of wiring mode and calibration methods of electric energy meter. It establishes the multiple data intelligent diagnostic model based on information such as current cutoff、 lose of phase、 voltage-loss and severe three-phase unbalance. By analyzing and comparing with the user data of Power User Electric Energy Data Acquire System, the model can automatically identify and diagnose abnormal power consumption behavior like stealing electricity. It also establishes a model for distinguishing the abnormal operating state of electric energy meter, which can realize automatic distinction of abnormal operating state of electric energy meter. 3rd International Conference on Machinery, Materials and Information Technology Applications (ICMMITA 2015) © 2015.
